Latest Patents

Esnault holds a patent for a method titled "Online control of rheology of building material for 3D printing." This patent describes a technique for placing a flowable construction material that includes a hydraulic binder to build structural components layer-by-layer. The method involves preparing a fresh flowable construction material made of Portland cement, fine limestone filler materials, fine sands, water, and a water-reducing admixture. Additionally, it may include a set or hardening accelerating admixture. The flowable construction material is conveyed to a deposition head, where it is placed through an outlet to form a layer of construction material. Before placement, a rheology-modifying agent is added to increase the yield stress of the material compared to its state during the conveying step. Esnault's innovative work in this area has the potential to revolutionize the construction industry.
